Query acceleration using intermediate summaries

ABSTRACT

A method and system for managing searches of a data set that is partitioned based on a plurality of events. A structure of a search query may be analyzed to determine if logical computational actions performed on the data set is reducible. Data in each partition is analyzed to determine if at least a portion of the data in the partition is reducible. In response to a subsequent or reoccurring search request, intermediate summaries of reducible data and reducible search computations may be aggregated for each partition. Next, a search result may be generated based on at least one of the aggregated intermediate summaries, the aggregated reducible search computations, and a query of adhoc non-reducible data arranged in at least one of the plurality of partitions for the data set.

TECHNICAL FIELD

The invention is directed to providing services for use by a customer, and more particularly, to providing search services to the customer over a network.

BACKGROUND OF THE INVENTION

Many companies install and maintain search software for use on a variety of distributed systems that can range from a single computer for a small business to a collection of servers and a plurality of user computer nodes for a large corporation. In the past, search reports based on relatively large sets of indexed data were time consuming to generate. To reduce latency in search report generation for a larger data set, intermediate summaries for reoccurring search reports for partitioned data have been periodically generated and stored in a separate index. Subsequently, a search report run on the data set would aggregate the corresponding pre-computed intermediate summaries to generate the search report in a relatively shorter period of time. However, the nature of different types of data and the structure of different search queries has made it difficult to manage and configure these intermediate summaries. For example, some partitions may include data that is highly reducible for a search query and other partitions may include data that is only marginally reducible for the same search query. Also, for a single set of data in a partition, it may be reducible for some queries but not others. Other difficulties include configuring the amount of data included in the partitions of the data set, such as adding newly identified data to a partition after intermediate summaries are generated. Consequently, systems that can manage search report generation for relatively large sets of data are the subject of considerable innovation.

DESCRIPTION OF THE VARIOUS EMBODIMENTS

The invention now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific embodiments by which the invention may be practiced. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the invention may be embodied as methods or devices. Accordingly, the invention may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.

Throughout the specification and claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise. The phrase “in one embodiment” as used herein does not necessarily refer to the same embodiment, though it may. Furthermore, the phrase “in another embodiment” as used herein does not necessarily refer to a different embodiment, although it may. Thus, as described below, various embodiments may be readily combined, without departing from the scope or spirit of the invention.

In addition, as used herein, the term “or” is an inclusive “or” operator, and is equivalent to the term “and/or,” unless the context clearly dictates otherwise. The term “based on” is not exclusive and allows for being based on additional factors not described, unless the context clearly dictates otherwise. In addition, throughout the specification, the meaning of “a,” “an,” and “the” include plural references. The meaning of “in” includes “in” and “on.”

Various embodiments now will be described more fully hereinafter with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. The embodiments may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the embodiments to those skilled in the art. Among other things, the various embodiments may be methods, systems, media or devices. Accordingly, the various embodiments may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.

For example embodiments, the following terms are also used herein according to the corresponding meaning, unless the context clearly dictates otherwise.

The term “query” as used herein refers to commands and/or sequences of commands that are directed for searching and/or retrieving data from a record datastore. Queries generally produce a result or results based on the form and structure of the particular query. Query results may be sorted and grouped based on the structure and form of the query. In at least one of the various embodiments, queries may includes operators and functions for calculating value based on the stored records, including functions that produce results sets that may include statistics and metrics about the portions of the record datastore. Structure Query Language (SQL) is a well-know query language often used to form queries for relational databases; herein queries may be described using a “SQL-like’ form for readability. However, the various embodiments are not limited to using SQL-like formatting for queries and other well know query languages and/or custom query languages may be employed consistent with what is claimed herein.

“Index”, “Indexer”, “Indexing”, and “Index Storage” as used herein may represent elements of described embodiments that may index and store data and events. Indexers may collect, parse, and store data to facilitate fast and accurate information retrieval. Index design may incorporate interdisciplinary concepts from linguistics, cognitive psychology, mathematics, informatics, physics, and computer science. Also, Indexes may reside in flat files in a data store on a file system which may be distributed and enables distributed computations. Index files may be managed to facilitate flexible searching and fast data retrieval, eventually archiving them according to a configurable schedule. During indexing, incoming raw data may be processed to enable fast search and analysis, the results of which may be stored in an index. As part of the indexing process, the indexer may add knowledge to the data in various ways, including by: separating a data stream into individual, searchable events; creating or identifying timestamps; extracting fields such as host, source, and source type; performing user-defined actions on the incoming data, such as identifying custom fields, masking sensitive data, writing new or modified keys, applying breaking rules for multi-line events, filtering unwanted events, routing events to specified indexes or servers, and the like. Also, for a reducible structure of a reoccurring search, the indexer can perform a logical sequence of actions on the data, e.g., computing averages, variances, root mean squares, or the like.

Briefly stated, various embodiments are directed towards a system and method for managing and configuring one or more different search reports for a data set that is partitioned based on a time of occurrence for a plurality of events. Data corresponding to each event may be arranged in a corresponding partition. In at least one of the various embodiments, a structure of a search query for a particular search report may be analyzed to determine if at least a portion of the query's logical computational actions are reducible. If so, the reducible search computations are performed on at least one of the partitions. Also, in at least one of the various embodiments, data in each partition is analyzed to determine if at least a portion of the data is reducible for a particular search report. If so, intermediate summaries are generated for the reducible data which may be arranged in one or more partitions. In response to a subsequent or reoccurring request for a particular search report, the corresponding intermediate summaries and reducible search computations may be aggregated for each partition. Next, a search result may be generated based on at least one of the aggregated intermediate summaries, the aggregated reducible search computations, and a search query of any remaining adhoc non-reducible data arranged in at least one of the plurality of partitions for the data set. Additionally, intermediate summaries and reducible search computations may be reused for more than one particular search report.

In at least one of the various embodiments, each partition of the data set is based on at least a time for an event. Also, in at least one of the various embodiments, the data may include time series data where each data record has a timestamp associated with it. Search reports for the stored time series data may be limited by a range of time (such as between one time and another, or data earlier than a given time, and the like) and/or provide search results ordered by a time (such as from earliest-to-latest or vice versa). Additionally, in at least one of the various embodiments, newly identified other data related to an event may be appended to a particular partition that corresponds to the event.

In at least one of the various embodiments, at least a portion of at least one partition of the data set can include adhoc data that is substantially unique/non-reducible for a particular search report. For example, in at least one of the various embodiments, if the amount of adhoc non-reducible data in a partition for a particular search report is substantially greater than reducible data, the process may stop generating further intermediate summaries for that partition for that particular search report unless more reducible data is appended to the partition. In at least one of the various embodiments, reoccurrences of the search report may be one of periodic, intermittent, or random.

In at least one of the various embodiments, a logical sequence of actions performed by a reducible search computation for a particular search report may be normalized for the partitioned data set. Additionally, in at least one of the various embodiments, a uniqueness value for at least a portion of the data in each partition for a particular search report may be determined. Also, a high uniqueness value may be employed to identify the non-reducible data and a low uniqueness value may be employed to identify reducible data in each partition for a particular search report. Additionally, the data may be stored in one or more data stores, and one or more computing devices may be employed to distribute the computing of intermediate summaries, reducible search computations, and search results for a plurality of different search reports.

The following briefly describes embodiments in order to provide a basic understanding of some aspects of the invention. This brief description is not intended as an extensive overview. It is not intended to identify key or critical elements, or to delineate or otherwise narrow the scope. Its purpose is merely to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

General Operation

FIG. 5 , illustrates a flowchart for general overview 500 of at least one of the various embodiments for processing a search query for a particular search report. Moving from a start block, the process steps to block 502 where a data set is arranged in a plurality of partitions based at least in part on separate events over time.

Stepping to block 504, reducible search computations for the particular search report are performed for data in at least one of the partitions. A search computation is a logical sequence of actions performed on data to generate a result. A reducible search computation might generate an average, a variance, a root mean square, or the like that can potentially be reused in one or more different search reports. In contrast, a non-reducible search computation might instead require accessing most if not all of the data in each partition each time a particular search report is requested. For example, the non-reducible search computation might involve computing a statistic that is grouped by the value of a high cardinality field, such as a user ID or an IP address. Since this type of computation is unlikely to be significantly reducible, the intermediate summaries would be on par with the size of the original data. In this case, the process would skip generating the intermediate summaries for this partition of the data or that particular search report. In at least one of the various embodiments, at least some of the reducible search computations may be generated by an application that also enables indexing of the data into one or more partitions that correspond to events over time.

Advancing to block 506, one or more intermediate summaries are generated for reducible data for the particular search report in each partition. Also, depending on the nature of the data in each partition, a partition may include one or more intermediate summaries, adhoc data, or a combination of both intermediate summaries and adhoc data. In at least one of the various embodiments, at least some of the intermediate summaries are generated by an application that also enables indexing of the data into one or more partitions that correspond to events over time.

At block 508, in response to a search query for a particular search report, the intermediate summaries and the reducible search computations that correspond to the search report are aggregated for the data set.

Then, at block 510, a search result is generated for the particular search report based at least one of the aggregated intermediate summaries, aggregated reducible search computations, and the processing of any remaining adhoc data in one or more partitions with the search query. Next, the process returns to performing other actions.

FIG. 6 illustrates overview flowchart 600 for processing intermediate summaries and reducible search computations for a particular search report for data that is arranged in a plurality of partitions. Moving from a start block, the process advances to block 602 where the data set is arranged in a plurality of partitions that correspond to a time of occurrence for events. At decision block 604, a determination is made as to whether the structure of a particular requested search report is reducible. If negative, the logic loops back to block 602. However, if the determination at block 604 is affirmative, the process flows to block 606 where reducible search computations are performed on data in each partition for the particular search report. The values generated by the reducible search computations are normalized for the data set.

At decision block 608, a determination is made as to whether reducible data is present in a partition for a particular search report. If true, the process advances to block 610, where the process generates intermediate summaries for reducible data in each partition for the particular search report. In some cases, a very small portion of data in each partition may be reducible, and/or the reduction in the data may not be significant for a particular search report. Consequently, even though some intermediate summaries may be generated, the process may determine to not continue to do so if the advantage (reduction in data to be processed for a particular search report) is relatively small.

Moving to block 612, newly identified data for an event may be appended to other data already arranged in a partition that corresponds to the event. Also, if the determination at decision block 608 was false (no reducible data in at least one partition for a particular search report), the process would jump to block 612 and perform substantially the same actions as discussed above.

At decision block 614, if a period of time since the last processing of the partitioned data set has not yet elapsed, the process loops until true and then loops back to block 602 where it performs substantially the same actions as discussed above.

FIG. 7 shows a flowchart of a general overview 700 for processing a request for a particular search report. Moving from a start block, the process advances to block 702 where a query for a particular search report is received.

At block 704, the available intermediate summaries for the particular search report from one or more partitions are aggregated. Similarly, at block 706, the available normalized reducible search computations for the particular search report from one or more partitions are aggregated.

Moving to block 708, the search query for the particular search report is performed on adhoc data that is non-reducible. Advancing to block 710, a result for the particular search report is generated based at least in part on the aggregated intermediate summaries, aggregated reducible search computations, and the query performed on the adhoc data. Next, the process returns to performing other actions.

FIG. 8 illustrates a schematic diagram of data set 800 that includes a plurality of data partitions 802, 804, 806, 808, 810, and 812 that correspond to events over time. As shown, partitions 802, 808 and 812 include non-reducible adhoc data for a particular search report. Partition 804 includes 100 percent intermediate summaries for the particular search report. Partitions 806 and 810 include partial intermediate summaries and partial adhoc data for the particular search report. Also, appended to partition 808 is newly identified data for the event that corresponds to the partition.

FIG. 9 shows an exemplary table of raw data that includes columns for time, name, size, and ip address on a server. Also, FIG. 10 illustrates an exemplary table of intermediate summaries that may be generated for a query that needs the average and maximum of the size field over time split by name. In addition to time and name, the table includes the count of the size field, the maximum of the size field, and the sum of the size field for each value of time and name. This may be because in at least one of the various embodiments a separate accounting of the count and the sum may be maintained to compute an accurate overall average (arithmetic mean).

It will be understood that figures, and combinations of actions in the flowchart-like illustrations, can be implemented by computer program instructions. These program instructions may be provided to a processor to produce a machine, such that the instructions executing on the processor create a means for implementing the actions specified in the flowchart blocks. The computer program instructions may be executed by a processor to cause a series of operational actions to be performed by the processor to produce a computer implemented process for implementing the actions specified in the flowchart block or blocks. These program instructions may be stored on some type of machine readable storage media, such as processor readable non-transitive storage media, or the like.

Furthermore, it will be understood that for at least one of the various embodiments, various types of data may be received and processed as described and claimed herein. And, at least one of the various embodiments is not limited to processing machine data.
